Your hip and waist measurements are the most important size when finding the perfect fit.
Measure around your body as shown.
Find your waist measure by leaning over to one side. Where your body naturally creases is your where you will place the tape. Measure parallel to the ground.
For your hip measurement, turn to the side and locate the fullest part of your booty. Place the tape around your body, parallel to the floor, around the widest and fullest part of your hips and tush.
If your measurements fall into different size categories, your hip measurement will be most accurate.
